Raspberry Pi SPI support #4

Closed smythcc closed 6 years ago

smythcc commented 6 years ago

It doesn't appear this utility supports interacting with an SD card connected via the SPI pins on the GPIO header. I point it at /dev/mmcblk2 but get a "Failed to send command: Function not implemented" response. Any thoughts on how this could be supported? (Possible driver/config issue?)

I think this command is not available when using the card in MMC (SPI) mode. Therefore it cannot be implemented.
